Assembly
Setup
• Assembly the swivel casters on the jack legs using lock washers and nuts provided.
• Assemble the legs (with the casters) to the jack's base, and slightly secure with the Allen socket
bolts and lock washers provided.
• Position the jack (with legs) on a hard level surface. Tighten the Allen socket bolts while all four
casters are contacting the floor and the jack apppears vertical to the floor.
• Locate the draw bar and the two hex bolts in the carton, Insert the draw bar into its sockets on the
cylinder, and secure with the hex bolts provided.
• Saddle assembly: Loosen the bolt from outside the saddle adapter. Mount the saddle adapter
onto the top of the piston rod. Once mounted, tighten the bolt and secure entire saddle assembly.
• Use the tilt adjusting knob to adjust the saddel angle to a relatively horizontal positon.
• Attach the two corner support brackets onto the uniersal saddle, and fasten with the hex bolts and
nuts.
• Locate the fixing bracket in the chain pack. Assemble the fixing bracket on the corner support
bracket and secure with the hook and screw caps. Assemble chains and chain hardware to the
corner support bracket.
• The chains and chain hardware are provided to secure the transmission, transfer box, or
differential to the saddle assembly by the different shape of their housing. When using, both ends
of the chain should be anchored to the bracket.
• To prevent oil leak during shipment, a shipping plug is used to ensure the best sealing function.
Remove the shipping oil plug, and replace it with vented oil plug provided.
• The reservoir tube is shipped filled with hydraulic oil. Beofre using the jack for the first time,
press the release pedal to open the release valve, and operate the foot pump 8-10 full strokes to
distribute the oil.
Operation
Bleed Air from the Hydraulic System
• Follow the vehicle's recommended service procedure for removal of the component.
• Position the jack under the vehicle.
• Raise the jack by operating the foot pump until the saddle reaches the component.
• Adjust the suport brackets to fit the component.
• Use the tilt crank to align the saddle with the component.
• Finish raising the jack to the component. Secure the chain assembly around the component.
Air can accumulate within a hydraulic system during shipment or after prolonged use. This entrapped
air causes the jack to respond slowly or feel "spongy". Follow the steps below to bleed the system :
To bleed the air in the oil system:
1. Pump the jack to the highest point where the first and the second stages are both at the
maximum height.
2. Get the help of another person to keep the release pedal depressed, and activate the foot pedal
about 15-20 times.
3. Let go if the release pedal; the air in the oil system should be bled successfully.
To bleed the air in the second cylinder:
1. Locate the air bleeder screw at the top nut, which is on the top of the first piston rod.
2. Pump the jack to its maximum height. Use an Allen socket wrench to loosen the air bleeder
screw for no more than two full rotations. Push the saddle assembly downward to purge the air
in the cylinder out until nothing but oil drains out of the bleeding hole.
3.Tighten the bleeder screw and double check. It may be necessary to repeat the above steps
several times.
